Abstract
An expandable intervertebral implant for insertion between vertebrae of a human spine is described. The intervertebral implant includes an upper body that engages a first vertebra of the human spine, a lower body that engages a second vertebra of the human spine, an insert, and an advancing element. The advancing element may engage the insert such that advancement of the advancing element causes the insert to at least partially rotate between the upper body and the lower body. Rotation of the insert may cause the insert to interact with at least a portion of the upper body or at least a portion of the lower body to increase a separation distance between the upper body and the lower body, thereby increasing a height of the intervertebral implant after insertion of the implant between the first vertebra and the second vertebra of the human spine.
